Description
The Greenlee 45057 Multi-Network Cable Tester is intended to verify
the continuity and pin configuration of various communication circuits.
It consists of a self-contained transmitter/receiver and a remote receiver.
The transmitter/receiver can be used alone to verify the integrity of a cable
prior to installation, or used with the remote receiver to test cable after
installation. The 45057 can be used to check Ethernet 10 Base-T, RJ-45,
RJ-11, Token Ring, USOC 4, USOC 6, USOC 8, EIA/TIA 568A, EIA/TIA
568B, AT&T 258A, BNC Coax Cable, and others.
The transmitter/receiver requires a single 9-volt battery; the receiver draws
its power from the transmitter and does not require a separate battery.
